Skis

Abstract

A ski has at least two downwardly-extending projections (10, 16, 16B), at least one on each side of the longitudinal axis of the ski, these being integral with the remainder of the ski separate members, in the form of an inverted channel member (7), the base (7A) of the channel, on the upper side of the channel member (7), lying above and being secured to the tail (1) of the ski, which extends between the side walls (7B) of the channel member (7). When the ski is placed on a flat horizontal surface, with the running face (3) of the ski lowermost, the tips (10A, 16A) of the projections (10, 16, 16B), at the lowermost extremities of the projections, will be separated only by an air gap from the surface.

I claim: 
     
       1. A ski having a turned up forward edged section, a trailing edged section with a tail end, and an intermediate edged section, the top of which latter section is provided with binding means for a ski boot, said sections forming a ski having an upper surface, and a running bottom face, said ski further comprising integral with the trailing edged section, and extending rearwardly therefrom has an inverted channel portion having a horizontal base substantially coplanar with the upper surface of said trailing section, and pair of side walls one of which depends downwardly from each side of the horizontal base in such manner that said side walls are disposed parallel to the side edges of the intermediate and trailing ski sections; each of said side walls having at least one recess along its lower edge and defining at least one projection extending downwardly from the horizontal base, the depth of each said projection being such that, when the running bottom face of the ski is laid on a flat horizontal surface, the lowermost tip of each said projection will be spaced slightly from and above said flat surface and a plane surface formed by said running bottom face to provide an air gap between said tip and said flat surface. 
     
     
       2. The ski as described in claim 1 wherein each of said side walls defines a plurality of projections spaced apart from each other and extending downwardly from said horizontal base, the depth of each of said projections being such that when the running bottom face of the ski is placed on a flat horizontal surface, the lowermost tips of the projections will be spaced slightly from, and above, the last said surface and the plane of the running bottom face to provide air gaps between said tips and said flat surface. 
     
     
       3. The ski as described in claim 2 wherein the projections are elongated in a direction parallel to the side edges of the ski sections. 
     
     
       4. The ski as described in claim 2 or claim 3 wherein each projection is spaced apart from the adjacent projections. 
     
     
       5. The ski as described in claim 4 wherein each projection has a forward convex lower edge which extends in a smooth curve both upwardly and forwardly, and a convex rearward lower edge which extends in a smooth curve both upwardly and rearwardly. 
     
     
       6. The ski as described in claim 1 wherein the channel member extends rearwardly of the tail of the trailing section of the ski by at least 10 cm. 
     
     
       7. The ski as described in claim 2 wherein the depth of each projection is between 2 and 10 millimeters.
